Defending isn't always easy, but it can be loads of fun. In this action defense game, you have to kill the enemies before they make it to the flag. Make sure you grab dropped ammunition after you kill them with no mercy. Use the left and right arrow keys to move and aim. Use the up key for a weapon punch and the down key for crouching and using an alternative fire. If you find yourself surrounded, press up for weapon punch and see what happens! Make sure every shot counts because you don't want to run out of ammo.
